Abstract

The dielectric properties of nematic liquid crystal (LC) mixtures are measured from 300 GHz to 1500 GHz. Measurements are performed in a standard THz TDS setup. Refractive index and extinction coefficient for parallel and perpendicular orientation are calculated and compared to results obtained at 19 GHz. The investigated mixtures are of interest for Terahertz devices as their properties stay almost constant from 19 GHz to 1500 GHz.
